For distribution networks with increasing PV integration, a local voltage regulation approach is suggested in . A very short-term solar generation forecast, a medium intelligent PV inverter, and a reduction of the AP are reported as forecast techniques.
High-penetration photovoltaic (PV) integration into a distribution network can cause serious voltage overruns. This study proposes a voltage hierarchical control method based on active and reactive power coordination to enhance the regional voltage autonomy of an active distribution network and improve the sustainability of new energy consumption.
Achieving energy balance within each region of the distribution network is facilitated through the collaborative strategy of photovoltaic storage. The voltage regional autonomy capability refers to the voltage regulation capacity of photovoltaic storage within each region of the distribution network.
As the integration of distributed photovoltaic systems within distribution networks escalates, the reactive power surplus of their grid-connected inverters undergoes a significant surge, which evolves into a pivotal management asset for voltage regulation within the distribution grid.
In addition, in , to prevent overvoltage problems in power distribution networks, the use of the battery has an important role and three various scenarios for grid conditions, are tested as the voltage control mode, mitigating reverse power flow mode, and scheduling mode.
